WEED-EXTERMINATOR.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, Enwix E. Jaoiisoh fa citizen of the U1'1ited 'States, residin at Newton, in the county of Harvey and tate of Kansas,haveinvented new and useful Improvements in \Veed-Exterminators, ofwhich the following is a specification.

This invention relates to weed extermi nators, the object of theinvention being, to provide a hand implement embodying a reservoir andmeans operable by contact with the ground for forming a hole in theground and admitting a predetermined quantity of liquid of such natureas to destroy or poison the. roots of the weeds causin the same to die.

TV-ith the above and other objects in view,

- the nature of which will more fully appear as the description1proceeds, the invention consists in the nove construction, combmation.and arrangement of parts as herein .long tapering tu fully described,lllustrated and claimed.

In the accompanying drawings :Figure 1 is a side elevation of a weedexterminator embod ing the present invention. F i 2 is a verticalsectional view through the ovver portion thereof taken on an enlargedscale.

The device comprises essentially a reservoir 1, which is referably inthe form of a iie, the same bein provided at its upper larger and with are uced portion or neck upon which is fitted a threadedfilling ea orclosure 2 by means of which any suita ble exterminating liquid, such asgasolene, kerosene and the likemay be introduced into the body of thereservoir.

Secured to the lower endof the reservoir is an inverted conical endpiece or nozzle 3 which is preferably mounted detachably' on the mainbody of the reservoir by a screw threaded connection as shown at4 inorder to give ready access to the valve arrangement on the interiorthereof.

Extending longitudinally within the lowerportion of the device is a stem5 of .a

and are held in place at the desired point on the stem 5 by means ofclamping nuts 7 and 8, arranged respectively above and beneath the disks6 and threaded upon the stem 5. Within the body of the implement, thereis also arranged an upper valve seat 9 While at a lower point there is asecond or lower valve seat 10, the valve 6 playing upward and downwardbetween the valve seat 9 and the other valve seat 10, while-the spacebetween said valve seats -forms a measuring chamber for the liquid,passing downward by gravity from the cone body of the reservoir 1'.'Thestem at or'near its upperendpasses through a guide 11 suitablyarranged within the lower end of the reservoir 1 while between saidguide 11 and an enlarged shoulder or seat 12 on the stem there isintroduced'a valve spring 13 the tension of which is exerted to thrustand hold the valve 6 in contact with the lower valve seat as showninFig.-2.

The nozzle section 3 may be swaged out ward as shown at 14 to form anannular groove for the retention of the lower valve seat 10 while thereservoir may be swaged outward as shown at 15, to form a correspendinggroove for the retention of the up er valve seat 9. y I i n theoperation, the lower" end of the point of the stem is thrust into theground forming a hole in the ground and causing the stem 5 to press thevalve 6 upward against the upper valve seat. This allows liquidcontained between the valve seats 9 and 10 to pass downward throughthenozzle and fill the hole formed by the stem 5 when the latter iswithdrawn. 'By forming the hole adjacent to the roots of the weed, theliquid is thus deposited in close proximity thereto and acts in shortorder to kill the weedr Upon lifting the implement from the ground, thespring 13 returns the valve quickly to the lower seat'and allows themeasuring chamber to again fill. The amount of liquid may be varied byincreasing or diminishing the number of disks 6 which constitute thevalve.

a longitudinally movable valve stem having In testimony whereof I affixmy signature 3 portion projecting outside and beyond the in presenr'e oftwo witnefiees. nozzle, and a valve carried by said stem and movablebetween the valve seats. said valve consistingv of a plurality ofsw-tions \\'11nu e and means for (-lamping Hm sex-How to l B. ll.'liinxi-zn,
